going to build some wind flags and i need some help

[antitactical]

I was wondering where do you get the pinwheels for a windflag . I was looking for a 7" propeller ( the oldschool garden plastic sunflower brown and yellow would work fine) .Ive searched the internet quite a bit but no luck. Any info would help thanks

I'm going to build some new ones myself and have been looking for a suitable bearing for the top of the vertical shaft, have'nt found anything yet any ideas?

We use the 3' long aluminum (tinsel) wind streamers on top of a short aluminum pole with a fishing swivel . We can actually guage wind speed by the degree of angle on the very sensitive streamers.
We have an anamometer on top of the house so it was easy to work out the calculation. IE: a 45 degree angle is a 10mph wind by the anamometer.
